salt, percent mass loss

Post by cristina »

Can someone PLEASE help me out with the following questions, I have no idea what it is asking let alone how to come up with an answer. I would appreciate it, thanks!

For the salt FeCl3.6H2O, calculate the percent mass loss if the salt decomposed by
a. simple loss of water
b. Typical decomposition of a hydrated salt with a 3+cation.[/b]

Obviously, the reaction is FeCl3.6H2O = FeCl3 + 6H2O
Now canculate molecular weights of FeCl3.6H2O and anhydrous FeCl3
The difference is the water loss.
Remember safety first! Check MSDS and consult with professionals before performing risky experiments.
